通过对制革工业含硫废水处理方法的探讨，并根据实验结果对真空内循环负压法处理含硫废水的机理进行了论证，提出了最佳工况条件，同时作了经济分析，为实际生产的运转成本、处理效果、设备构型等方面提供了可靠依据。

Several ways of treating sulfur-containing wastewater in tanning industry are discussed. Based on experimental results, the mechanism of vacuum inner circulation negative pressure is demonstrated and the optimal conditions are confirmed. At the same time, economic analysis has been made so as to present reliable basis for the practical running cost, treatment effect and equipment construction.
